Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a domestic sewage and solid waste separation device. Background Art

[0002] Domestic sewage is wastewater discharged from residents' daily lives, mainly from residential buildings and public buildings, such as residences, offices, schools, hospitals, shops, public places and toilets of industrial enterprises. There are a large number of solid wastes in domestic sewage, which must be treated before discharge. Traditional domestic sewage is basically transported from different areas to the main pipeline through an underground pipe network. The main pipeline transports the sewage to the sewage treatment plant and performs solid-liquid separation. This makes the treatment pressure of the terminal sewage treatment plant relatively large, resulting in low sewage treatment efficiency and limiting the sewage treatment peak of the sewage treatment plant. The current sewage treatment system lacks a device that can pre-filter the solid waste of sewage in each pipe network. In this regard, the utility model proposes a domestic sewage solid waste separation device to achieve pre-separation of solid waste in sewage and reduce the pressure of sewage treatment at the terminal sewage treatment plant. Utility Model Content

[0003] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the utility model is to provide a domestic sewage-solid waste separation device, which can filter, intercept and squeeze the solid waste in domestic sewage in advance for discharge treatment, thereby reducing the pressure of sewage treatment in the terminal sewage treatment plant and will not affect the normal discharge of sewage in each pipe.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. It should also be noted that, for ease of description, only the parts related to the utility model are shown in the drawings.

[0029] Example: Reference Figure 1-4 A domestic sewage-solid waste separation device shown in the figure comprises a water inlet pipe 1, a sewage pipe 4 and two collecting boxes 5. The bottom end of the water inlet pipe 1 is fixedly connected to two branch pipes 2. The bottom ends of the two branch pipes 2 are fixedly connected to separation components 3. The bottoms of the two separation components 3 are connected to the sewage pipe 4.

[0030] The separation component 3 includes a separation bin 301, in which a filter cartridge 302 is fixedly passed through the separation bin 301, the bottom end of the branch pipe 2 passes through the separation bin 301 and is connected to the filter cartridge 302, one end of the filter cartridge 302 is fixedly connected to an extension barrel 303, a plug plate 304 is slidably fitted in the extension barrel 303, a pressure sensor is embedded and fixed on the end face of the plug plate 304, the other end of the filter cartridge 302 is fixedly connected to a discharge barrel 305, in which an extrusion column 306 is slidably fitted, the collecting box 5 is located directly below the extension barrel 303, a plurality of filter holes are provided on the side surface of the filter cartridge 302, a sewage cavity 312 is formed between the separation bin 301 and the filter cartridge 302, an outlet pipe 307 is fixedly connected to the bottom of the side surface of the separation bin 301, and the bottom end of the outlet pipe 307 is fixedly connected to the sewage pipe 4.

[0031] The domestic sewage and solid waste separation device is in accordance with Figure 1As shown, the device is installed vertically and fixed, and the top of the water inlet pipe 1 is connected to the sewage conveying pipe of the area. After the domestic sewage enters the water inlet pipe 1, it will be evenly divided into the two branch pipes 2, and then conveyed to the two separation components 3 through the two branch pipes 2. The two separation components 3 can quickly intercept and separate the solid waste in the sewage by alternating operation, and can automatically discharge the solid waste from the device;

[0032] After the domestic sewage enters the filter cartridge 302, the filter cartridge 302 filters and intercepts solid waste, so that the solid waste is temporarily stored in the filter cartridge 302. The filtered wastewater enters the sewage cavity 312 and is collected into the sewage pipe 4 through the outlet pipe 307. The squeezing column 306 is controlled to slide into the filter cartridge 302. As the squeezing column 306 slides, the squeezing column 306 can close the connection between the branch pipe 2 and the filter cartridge 302, forcing the wastewater to flow only to the other branch pipe 2. Since one end of the extension tube 303 is closed by the plug plate 304, as the squeezing column 306 continues to advance, the solid waste between the squeezing column 306 and the plug plate 304 will be compressed, and the squeezed wastewater enters the sewage cavity 312 through the filter hole. The pressure sensor is used to monitor The pressure value on the end face of the plug plate 304 is measured. When the pressure on the end face of the plug plate 304 reaches a preset value, the plug plate 304 slides outward, and the moving speed of the plug plate 304 is the same as the moving speed of the extrusion column 306. The plug plate 304 gradually slides out of the outer tube 303. At this time, the extrusion column 306 continues to advance, thereby being able to push the solid waste out of one end of the outer tube 303 and drop it into the collection box 5, thereby achieving filtration, interception and extrusion discharge treatment of the solid waste in the sewage. After the solid waste is separated and discharged, the plug plate 304 and the extrusion column 306 slide synchronously, the plug plate 304 re-seals the outer tube 303, the extrusion column 306 slides out of the filter tube 302 and returns to the discharge tube 305 again, and then the other separation component 3 starts to work.

[0033] In order to control the squeezing column 306 to slide in or out of the filter cartridge 302, in this embodiment, a second hydraulic cylinder 313 is fixedly installed on the peripheral side of the extension cylinder 303, and a connecting plate 314 is fixedly installed on the output end of the second hydraulic cylinder 313. A strip groove 315 is provided on the peripheral side of the discharge cylinder 305. One end of the connecting plate 314 passes through the strip groove 315 and is fixedly connected to the squeezing column 306. The outer side of the squeezing column 306 and the inner side of the filter cartridge 302 are gap-matched, and the connecting plate 314 slides in the strip groove 315. The expansion and contraction of the second hydraulic cylinder 313 drives the connecting plate 314 to slide in the strip groove 315, thereby controlling the squeezing column 306 to slide in or out of the filter cartridge 302. The sliding cooperation between the connecting plate 314 and the strip groove 315 enables the squeezing column 306 to move horizontally in a straight line stably.

[0034] In order to be able to more effectively control the plug plate 304 to slide in or out of the epitaxial tube 303, in the present embodiment, a sealing plate 311 is fixed to one side of the plug plate 304, a connecting column 310 is fixed to one side of the sealing plate 311, a side plate 309 is fixed to one end of the connecting column 310, a first hydraulic cylinder 308 is fixed to one end face of the separation chamber 301, an output end of the first hydraulic cylinder 308 is fixedly connected to the side plate 309, a pressure sensor is electrically connected to the controller on the first hydraulic cylinder 308, and the outer side surface of the plug plate 304 is gap-matched with the inner side surface of the epitaxial tube 303. The pressure sensor transmits the pressure on the end face of the plug plate 304 to the controller on the first hydraulic cylinder 308. When the pressure reaches the preset value, the first hydraulic cylinder 308 pushes the side plate 309 to move horizontally, and the plug plate 304 slides out of the outer tube 303. When the solid waste is discharged, the first hydraulic cylinder 308 contracts and pulls back the side plate 309, so that the plug plate 304 enters the outer tube 303. The sealing plate 311 and the outer tube 303 approach and fit each other to seal the outer tube 303. During this period, the extension and retraction speed of the first hydraulic cylinder 308 is the same as the extension and retraction speed of the second hydraulic cylinder 313.

[0035] In order to enable the side plate 309 to move laterally and improve the sealing effect of the end of the epitaxial tube 303, further, in this embodiment, a group of guide rods 317 are fixed to one end surface of the separation chamber 301, one end of the guide rod 317 slides through the side plate 309, and a rubber sealing pad 316 is fixed to one side of the sealing plate 311. The setting of the guide rod 317 can enable the side plate 309 to move laterally along a straight line, and the setting of the rubber sealing pad 316 plays a sealing role, so that the contact between the sealing plate 311 and the epitaxial tube 303 is tighter.

[0036] In order to improve the stability and structural strength of the device and reduce the obstruction caused by solid waste to the movement of the extrusion column 306, further, in this embodiment, the two separation components 3 are symmetrically arranged relative to the water inlet pipe 1, and the end faces of the discharge barrel 305 in the two separation components 3 are fixedly connected to each other, so that the two separation components 3 are connected as a whole, thereby improving the structural strength and stability of the device. An annular blade 318 is provided at one end of the extrusion column 306, and the annular blade 318 can easily cut off the solid waste at the connection between the branch pipe 2 and the filter barrel 302, so that the extrusion column 306 can slide stably in the filter barrel 302.

Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model.
